Keto Lunchbox Omelette – The Perfect Grab & Go Lunch

Keto Lunchbox Omelette – The Perfect Grab & Go Lunch

Last year, I thought it was about time to get in control of our budget and spending. After a few quick calculations there was an obvious red flag – eating work lunches from cafes, restaurants and takeaway shops was costing us a fortune! Enter the easiest grab and go keto lunch – a simple oven baked omelette.

We eat this most days now – cut into squares and into the freezer between a couple of pieces of greaseproof paper, and you have lunch made for the week. You can eat this hot or cold. I often make a double or even triple batch every few weeks and we are set – and saving so much money.

The beauty of this dish is that you can use whatever you have in the fridge that needs to be cooked/used. It is very versatile and these suggestions are just a start.

In the image, I used baby spinach leaves and feta which created a decadent, tasty and satisfying lunch.

Suggested flavours/ add ins

Feta cheese

Cooked chicken/other cooked meats

Capsicum – either sauted before with paprika, or diced and put in raw

Spinach leaves, or frozen spinach that is defrosted and excess moisture squeezed out

Cream cheese in small dollops throughout or your favourite low carb dips


Spring onion, small amounts of brown onion or red onion

Seasonings: Oregano, rosemary, basil, paprika, garlic, harissa seasoning, Mexican seasoning etc etc



Chorizo sausage

Lunchbox Omelette

A simple base recipe for a quick and easy lunch - cook ahead on the weekend to make preparing lunches a breeze. Eat hot or cold. 

Prep Time 15 minutes
Cook Time 45 minutes
Total Time 1 hour

Calories 517 kcal


  • 8 Large Eggs
  • 1 cup Cream
  • 300 grams Bacon roughly 6 rashers
  • 1 tsp salt
  • 1 tsp pepper
  • 1 cup grated cheese whatever you have on hand


  1. Preheat oven to 180C / 356F and grease a casserole dish or baking pan. Usually deeper is better for me, so I like using a dish that is about 10cm x 15cm.

    Fry off the bacon until brown, it doesn’t need to get crispy as it goes in the mixture.

    Whisk eggs, cream, salt and pepper. If you are using other spices, add them to this mix.

    Stir in the cooked bacon and pour into your prepared baking dish.

    Add any additional mix ins to the baking dish and distribute evenly.

    Add half of the grated cheese into the mixture and stir to distribute, then sprinkle the remaining cheese on top. 

    Bake for 40 - 45 minutes until golden brown and set in the centre. Let it cool in the dish and then cut into 6 squares. Wrap in foil to freeze, grab out the night before and lunch is ready to go! Great reheated for lunch or cold.

Hi Rachel it looks like you have added silver beat but it is not in the ingredients is that correct if so fresh or frozen and how much

Hi Judy, as in the notes section you can add whatever you want to this. I regularly add baby spinach, around 3 cups, sautéed down in the same frying pan after the bacon is cooked. I also like adding shredded cooked chicken so my husband gets more protein in his lunch!

I have issued freezing these. Water tends to absorb by eggs becoming tasteless . How to resolve?

Hi there! Hmm I freeze them all the time and then my husband reheats them in the microwave at work. I cut it up and freeze in a tupperware container with baking paper in between. Were you using just the base recipe or did you add some different things?
